This read-create RowStatus object governs adding, modifying, or deleting a VSI controller configuration entry, with createAndGo used to add a new row and destroy used to remove one; once the row is active, its other columnar objects can no longer be modified. An administrator uses this to provision a new controller definition or retire an old one, keeping in mind that further changes to that controller's other settings require the row to not yet be active. For example, setting cvcConfRowStatus to destroy on an obsolete external controller entry removes its configuration from the switch.
